I want to clarify maybe some of you asking why should you buy Zenfone 2 if there is already Zenfone 6, 4 and 5?

Zenfone 6 refers to its screen size which is 6 inches and it is within the same line with Zenfone 4 (4 inches screen) and 5 (5 inches screen), making them the first models (First Generation) of Zenfone.Zenfone 2 is their latest model (2nd Generation)
